Why are genes with a lower rate of recombination typically inherited together?

a. The likelihood of a crossover event between these two genes is low.

b. The number of genes in a cell is greater than the number of chromosomes.

c. Alleles are paired together during meiosis.

d. Chromosomes are unbreakable.

e. Genes align that way during metaphase I of meiosis.

Answer #1

When two genes are present near on a chromosomes, then there are low chances of crossing over between them and low chances or recombination. And if the distance between the genes is large (understand by taking eg. of two genes present on tips of a chromosome) , then there are more chances that crossing over can take place between them because large portion of chromosomes is present between them. If the chances of crossing over are more then the chances of recombination is also more as recombination is formation of new combinations by crossing over.

So, correct answer is (a) the likelihood of a crossover event between these genes is low.

Please give a thumbs up if the answer helped you. Thank you :)

Cholera and other diarrheal diseases cause nearly 2 billion cases of diarrhea annually. Cholera toxin and other bacterial toxins cause the intestine to secrete fluid into the lumen of the gut, depleting the extracellular fluid (ECF) volume. If fluid loss is not matched with fluid intake (law of mass balance), the result is severe dehydration, circulatory collapse, and even death. Drinking a rehydration solution is the most rapid and effective way to replace the large volumes of water lost by...
